Download PC Access Guard
Supported on various Windows platforms such as Windows 95, 98, 2000, NT, Me, XP, and Vista systems, this free to use software application is intended to help users secure their system while they are away for short durations. PC Access Guard, as its name suggests, prevents unauthorized access to your system. This tool is simple to configure and can be activated from the tray icon, after it has been installed. Once this utility is initiated, any keystroke or mouse click results in an alarm being activated. Once the designated password is typed in, the alarm automatically switches off. If the password is incorrect, the program shuts down your system. During system restart the application again monitors your access.
